The effect of dibenzylsulfoxide and sodium phosphate on the stress corrosion cracking of steels

Abstract

This article aims to study the inhibition of Stress Corrosion Cracking (SCC) of steels (22K and OCH18N10T) in citric acid and sodium chloride. The effect of the investigated inhibitors; dibenzylsulfoxide (DBSO) and sodium phosphate (Na₃PO₄) was established by means of slow strain rate technique (SSRT). It was observed that DBSO positively influences the susceptibility of given steels to SCC. It was found that sodium phosphate inhibits the SCC of 22K, but increases the susceptibility of OCH18N10T steel to SCC.
